Large well defined high atteunation mass in the left psoas/iliopsoas extending caudally lateral to the femoral artery into the muscle groups of the medial aspect of the thigh.
This abuts the acetabulum, but without cortical irregularity.
The bladder and uterus are displaced medially.
A few reactive left groin nodes.
Upper abdomen normal.
Comment: Left iliopsoas mass. This may well represent an organised haematoma, however in view of this being evident for more than a month without resolution and the manner in which it extends into the upper thigh an alternative diagnosis such as a sarcoma merits thought.
It is amenable to ultrasound guided biopsy should this wish to be considered.
